This one has been debunked comprehensively. Aside from the fact that the "hidden" pendulum is pretty suspect and brings back memories of earlier "perpetual motion devices" that had hidden motors or windup energy sources the fact that the magnets will lose magnetization after some time clearly demonstrates that this is neither free energy nor perpetual motion.

In the video they state it's only 90% "there". But I really enjoyed the device, it's a pretty cool piece of art.
